Abstract

Patente de Invenção: <B>"PROCESSOS PARA A PREPARAçãO DA TIOXANTONA E DERIVADOS DA MESMA"<D>. é descrito um processo para a preparação de tioxantona e derivados da mesma. No processo, um composto aromático, tal como o cumeno é reagido com o ácido tiossalicílico (TSA) ou ácido ditiossalicílico (DTSA), na presença do ácido sulfúrico. A mistura de reação que inclui a tioxantona ou um derivado da mesma é em seguida destilada sob pressão reduzida para recuperar o composto de tioxantona.
